| 模具透气钢特性是降低注射压力,减少成型和保压时间。降低和消除成型件的内应力,防止产品的变形和曲翘。表面皮纹的塑料零件,由于高温高压产生的亮光皮纹,能解决要求亚光的表面。由于模具分型面的紧密配合,可以解决开模困难等情况。解决通常利用顶针、镶件等无法提供足够表面区域以容纳可能产生的大量气体等诸多问题,避免了利用分型面或其他排气系统而产生的飞边及其他瑕疵。可使由于浇口偏位、壁厚不匀、壁薄产品等较难成型问题得到解决和缓解。由于成型材料高温产生的气体和模具腔内快速聚压产生的烧焦、流痕、缺料、吸气造成的零件变形等缺陷能得到充分解决。提高成型生产效率,节约生产成本。 The characteristics of mould gas permeable steel are reducing injection pressure, reducing molding and holding time. Reduce and eliminate the internal stress of forming parts, prevent the deformation and warpage of products. The plastic parts with skin lines can solve the problem of matte surface due to the bright skin lines produced by high temperature and high pressure. Because of the close fit of the parting surface of the die, the difficulty of opening the die can be solved. It can solve many problems such as using thimbles, inserts and so on, which can not provide enough surface area to accommodate the large amount of gas that may be generated, and avoid the flash and other defects caused by using parting surface or other exhaust system. Because of gate deviation, uneven wall thickness, thin wall products and other difficult forming problems can be solved and relieved. The defects such as the gas produced by the high temperature of the forming material and the scorch, flow mark, lack of material and the deformation of the parts caused by the rapid agglomeration in the mould cavity can be fully solved. Improve the efficiency of molding production and save production cost. |
